摘要

本文在单核子交换图的基础上，对弹性\(pd\)后向散射进行了相对论性研究。通过求解Minkowski空间中具有相对论可分势的Bethe-Salpeter方程得到的相对论氘核波函数进行了计算。计算了初始质子动量高达7.3 GeV/c时反应的非极化微分截面和部分极化观测值。所得结果与其他作者的计算结果进行了比较。

Relativistic One-Nucleon Exchange for the Proton-Deuteron Backward Scattering

The article is devoted to the relativistic study of elastic \(pd\) backward scattering based on the one-nucleon exchange diagram. Calculations are performed using relativistic deuteron wave functions obtained by solving the Bethe–Salpeter equation in the Minkowski space with relativistic separable potentials. The unpolarized differential cross section as well as some polarization observables of the reaction for initial proton momentum up to 7.3 GeV/c are calculated. The obtained results are compared with the calculations of other authors.
